Problems with Z3ta+ 1 and Cubase 6

Hi,

Been having a problem recently, in previous versions of Cubase I was able to use Z3ta+ as both an instrument, and as an insert, I was able to use the presets in Z3ta+ as effects on any track, instrument or audio.

But on Cubase 6, I am unable to do this, and can only use it as an instrument, does anyone have any idea of why this could be?

I’m using Windows 7, on a PC.

Has anybody else had this problem at all?
